Ubuntu youtube no sound in firefox

I was continuously facing problem with sound while playing youtube using firefox. The youtube inturn uses gstreamer library to render the sound.

Finally got sound working after installing restricted packages!

Run "sudo apt-get install ubuntu-restricted-extras"

Paly and check your youtube for sound.

To delete windows partition from ubuntu.

1) Command to see the partition
sudo fdisk -l
2) Mount the windows partition
sudo mount /dev/sda1 /mnt/
3) Look for the files and verify the data
ls -rlt
4)Then look for the available file system
sudo mkfs.
5)Create the new file system
sudo mkfs.ext3 /dev/sda1
6)Finally mounting the created partition
sudo mount /dev/sda1 /mnt/

To change the file system.
sudo vim /etc/fstab

To remove windows during bootup
cd /boot/grub/
sudo vim menu.lst
sudo grub-install /dev/sda
